摘要
研究了菊科旋覆花属植物羊耳菊根的化学成分,从其甲醇提取物中分离得到东莨菪苷(Ⅰ),二十八烷酸(Ⅱ),三十三烷(Ⅲ)以及5个神经酰胺类化合物的混合物,分别为(2S,3S,4R,8E)-2-[(2′R)-2′-羟基二十二烷酸酰胺]-十八烷-1,3,4-三醇(Ⅳ),(2S,3S,4R,8E)-2-[(2′R)-2′-羟基二十三烷酸酰胺]-十八烷-1,3,4-三醇(Ⅴ),(2S,3S,4R,8E)-2-[(2′R)-2′-羟基二十四烷酸酰胺]-十八烷-1,3,4-三醇(Ⅵ),(2S,3S,4R,8E)-2-[(2′R)-2′羟基二十五烷酸酰胺]-十八烷-1,3,4-三醇(Ⅶ),(2S,3S,4R,8E)-2-[(2′R)-2′-羟基二十六烷酸酰胺]-十八烷-1,3,4-三醇(Ⅷ)。以上化合物均为首次从该植物中分离得到。
Objective : To study the chemical constituents of the root of lnula cappa. Method : The compounds were isolated and purified by recrystallization and chromatography with silica gel column and Sephadex LH-20 column. Their structures were identified by physico-chemical properties and spectral analysis. Results: Seven compounds were isolated as scopolin( Ⅰ ), octacosanoic acid( Ⅱ ), tritriacontane( Ⅲ ), (2S,3S,4R,8E) -2-[ (2'R) -2'-hydroxydocosanosylamino ] -octadecane-1,3,4-triol( Ⅳ ), (2S,3S ,4R,8E) -2-[ (2' R) -2'-hydroxytricosanosylamino ] -octadecane-1,3,4-triol ( Ⅴ ), ( 2S, 3 S, 4 R, 8 E ) -2- [ ( 2' R ) -2'-hydroxytetracosanosylamino ] -octadecane-1,3,4-triol ( Ⅵ ) , ( 2S,3S,4R, 8E) -2-[ ( 2' R) -2'-hydroxypentacosanosylamino ] -octadecane-1,3,4-triol ( Ⅶ ) , ( 2S,3S ,4R ,8E ) - 2- [ (2'R) -2'-hydroxyhexacosanosylamino ] -octadecane-1,3,4-triol ( Ⅷ ). Conclusion : All compounds were isolated from lnula cappa for the first time. Key words lnula cappa; Chemical constituents
